Last week my boyfriend and I almost had sex but

Patient

Q:Last week my boyfriend and I almost had sex but we didn't. He had his penis in contact with my vagina and he precumed. I am on and off birth control but I started taking it on time the following day. 6 days later, I missed a pill. And now today ( a week after seeing my boyfriend) I have bloodish/brownish discharge with slight cramping. Is it from missing my pill or could I be pregnant?
